About

I'm a hands-on Machine Learning Engineer who builds end-to-end AI solutions while leading technical teams. Over 8+ years, I've learned that the best ML work happens when you combine deep technical expertise with the ability to move fast, make strategic decisions, and ship products that users actually interact with. I specialize in NLP and LLM applications: fine-tuning language models, building RAG systems, developing AI Agents, and deploying models that handle real-world text at scale. Beyond NLP, I work across the full ML spectrum: classification, regression, clustering, recommendation, and forecasting. I've built and deployed solutions across fintech, insurtech, real estate, and retail, working directly with C-level executives to translate business challenges into technical strategies that drive measurable results. I build and mentor high-performing teams while designing MLOps infrastructure to support production-grade AI solutions.
